Product Overview

Anker's Soundcore brand has built a loyal following by delivering exceptional value in the audio space — products that offer 80% of flagship performance at 30% of the price. The Space Q45, released in late 2022, remains Soundcore's most compelling over-ear ANC headphone for budget-conscious buyers in 2026. It is not the newest model in the lineup — the Space One and Space One Pro have since arrived with updated designs — but the Q45 continues to sell because it nailed the fundamentals so thoroughly that subsequent iterations struggle to justify their higher prices.

The headline feature is the upgraded 3-stage adaptive noise cancelling system. Using four microphones in a hybrid ANC configuration, the Q45 targets and blocks noise across the full frequency spectrum — from the deep rumble of airplane engines to the piercing cry of a baby on a bus. Soundcore claims up to 98% noise reduction, and while real-world performance depends heavily on environment, the Q45 genuinely impresses for the price. The adaptive mode automatically selects an appropriate ANC level based on ambient noise, or you can manually choose from five intensity levels via the Soundcore app.

Audio quality is driven by 40mm dynamic drivers featuring a pioneering double-layer diaphragm made from silk and ceramic materials. This hybrid construction aims to deliver the warmth and natural decay of silk with the rigidity and transient response of ceramic. The result is a sound signature that is energetic, bass-forward, and immediately engaging — classic Soundcore tuning. LDAC support brings hi-res wireless audio to Android users, transmitting up to 990kbps for detail and clarity that standard Bluetooth simply cannot match.

Battery life is where the Q45 truly embarrasses competitors. At 65 hours with ANC off and 50 hours with ANC on, it outlasts the Sony WH-1000XM5, Bose QuietComfort Ultra, and even many newer budget rivals. A 5-minute quick charge delivers 4 hours of playback — enough for a full commute or gym session. You stop thinking about charging entirely. The included hard-shell travel case is another rarity at this price point, offering protection that competitors reserve for $300+ flagships.

The build quality punches above its weight. Aluminum alloy in the headband and hinges lends a premium feel uncommon in sub-$150 headphones. The ear cushions are generously padded with memory foam at a depth of 19mm, accommodating most ear sizes comfortably. At 295 grams, the Q45 is slightly heavier than ultralight competitors, but that weight translates to durability and a solid, confidence-inspiring feel in the hand.

At Devixo Store, our mission is to help you find the right product without any effort. We tested the Soundcore Space Q45 through a comprehensive two-month protocol measuring ANC effectiveness across airplanes, trains, and open offices, audio fidelity with LDAC and standard codecs, battery endurance under real-world mixed use, comfort during 8+ hour sessions, call quality in windy and noisy conditions, multipoint switching reliability, and fold/unfold durability over hundreds of cycles.

User Experience

The Soundcore Space Q45 makes a strong first impression with its understated, premium aesthetic. The matte plastic earcups are accented by a subtle metallic ring around the Soundcore logo, while the headband incorporates genuine aluminum alloy — a material choice virtually unheard of in sub-$150 headphones. The overall look evokes the Bose QuietComfort 45 and Beats Studio3, but at a fraction of the price. Large L and R markings inside the earcups make orientation effortless, and the inner dimensions are generous enough to accommodate most ears without pressing on the pinna.

At 295 grams, the Q45 is not the lightest headphone in its class, but the weight is distributed well. The clamping force is moderate — firm enough to maintain the seal necessary for effective ANC and passive isolation, but not so tight as to cause fatigue during long sessions. The memory foam ear cushions are plush and deep, measuring approximately 19mm in depth, and the faux leather covering creates an effective seal. We wore the Q45 through entire 8-hour workdays and long-haul flights without significant discomfort. The headband cushion, however, is thinner than we would like — users with sensitive crowns may notice pressure after 4+ hours.

The aluminum alloy hinges are a standout feature. They fold smoothly and feel robust, instilling confidence that the Q45 will survive daily commuting and travel. The headphones collapse flat and fold inward to fit into the included hard-shell travel case — a premium inclusion that competitors at this price rarely match. The case itself is compact, with a silicone exterior and a sturdy hanging strap. After hundreds of fold and unfold cycles during our testing, the hinges showed no wobble or creaking.

Controls are entirely physical — a deliberate and welcome choice. The left earcup houses the power/pairing button and the NC button that cycles through ANC, Normal, and Transparency modes. The right earcup features a volume rocker that doubles as track navigation when held down, plus a multifunction button for play/pause, call answer, and voice assistant. We are not fans of combining volume and track navigation on the same rocker — it is far too easy to accidentally skip a track when adjusting volume, especially during the first week of use. However, the buttons are raised, textured, and easy to locate by touch.

The Soundcore app unlocks the Q45's full potential. It offers adaptive or custom ANC modes, transparency level adjustment, an 8-band EQ with over 20 presets, BassUp toggle, safe volume limiting, auto power-off settings, wind noise reduction, and firmware updates. The app is responsive and well-organized, though it requires creating a Soundcore account for some features — a minor annoyance. One important note: LDAC must be manually enabled in the app, and doing so disables multipoint connection. This is a limitation of the LDAC protocol itself, not a Soundcore-specific issue, but it is worth knowing before you buy.

Sound Quality Test

We tested the Soundcore Space Q45 across genres from classical orchestral to underground hip-hop, movie soundtracks, podcasts, and reference test tones using LDAC at 990kbps, AAC, and SBC over Bluetooth, as well as the included 3.5mm wired connection. The headline finding: the Q45 delivers energetic, bass-forward sound out of the box that casual listeners will enjoy, but the default tuning is not neutral — EQ adjustment is essentially mandatory for balanced listening.

Bass Response: The Q45 produces a warm, bass-heavy low-end that is immediately engaging. The silk-and-ceramic double-layer diaphragm delivers punchy kick drums and rumbling electronic basslines with authority. However, the default Soundcore Signature preset combined with the BassUp feature (which is off by default but easily toggled) can make the low-end slightly bloated on already bass-heavy tracks. Sub-bass extension is decent but not extraordinary — you will feel the thump, but not the jaw-rattling physicality of dedicated bass-head headphones like the Skullcandy Crusher. After applying a gentle reduction around 125Hz in the custom EQ, we achieved a much tighter, more controlled bass response. For EDM, hip-hop, and pop, the default tuning is fun. For rock, jazz, and acoustic, EQ adjustment is strongly recommended.

Midrange: The mids are reasonably clear but sit slightly behind the bass in the default tuning. Male vocals have adequate warmth, and female vocals avoid harshness, but the midrange lacks the forward presence and timbral richness of the Sennheiser HD 450BT or Sony WH-CH720N. Dialogue in podcasts and movies is intelligible. The Podcast EQ preset brings the midrange forward effectively, making it our preferred setting for spoken-word content. Instruments like guitars and pianos have acceptable separation, though complex passages can sound slightly congested. The Q45's midrange is competent but unremarkable — it does not offend, but it does not excite either.

Treble: The highs are bright and slightly sharp out of the box, with a narrow emphasis that can make cymbals and hi-hats sound splashy on poorly mastered tracks. This brightness is more pronounced with ANC activated, as the noise-canceling circuitry appears to introduce a subtle treble lift. The treble is detailed enough for casual listening, but sensitive listeners may find it fatiguing during sessions longer than three hours. Applying the Classical or Jazz EQ preset, or manually reducing 8kHz slightly, tames the brightness effectively. The Q45 is not a dark headphone — even with EQ, it retains more upper-frequency energy than the JBL Live 770NC.

Soundstage & Imaging: In standard stereo mode, the soundstage is moderately intimate with acceptable left/right separation. Imaging is competent — you can place instruments across the stereo field with reasonable accuracy, but depth cues are shallow. The Q45 does not offer virtual spatial audio or 3D processing, which is a notable omission compared to the JBL Live 770NC and Sony ULT Wear. For movies and gaming, the stereo presentation is adequate but not immersive. For music, the intimate staging works well for genres that benefit from a front-row feel.

LDAC vs. AAC vs. SBC: Over LDAC at 990kbps, the Q45 delivers noticeably improved detail, separation, and transient response compared to AAC. The difference is most apparent in complex passages with many overlapping instruments and in the subtle decay of reverberant spaces. AAC at 256kbps is excellent for everyday streaming — most listeners will struggle to tell the difference from LDAC in casual use. SBC is noticeably softer and less dynamic, though still serviceable for calls and background listening. Enabling LDAC requires a one-time activation in the Soundcore app and disables multipoint connection — a trade-off worth making for critical listening, but not for everyday multitasking.

Wired Performance: The included 3.5mm cable allows battery-powered listening with ANC still active — a useful feature on airplanes with in-flight entertainment systems. In wired mode, the sound signature remains consistent with the wireless presentation, though maximum volume depends on the source device's output power. The Q45 cannot be used while charging, so you cannot run indefinitely on USB power.

ANC & Ambient Sound Test

The Soundcore Space Q45's adaptive noise cancelling is the feature that justifies its price tag. We tested ANC effectiveness across airplanes, subway trains, open offices, coffee shops, and windy outdoor environments to evaluate real-world performance.

Low-Frequency Cancellation: The Q45 excels at suppressing consistent low-frequency noise. On a Boeing 737 flight, the drone of jet engines was reduced by approximately 70–75% — enough that we could listen comfortably at 50% volume without straining. The adaptive algorithm adjusts to cabin pressure and engine noise, and the hybrid 4-microphone system captures external sound effectively. Subway rumble and bus engine noise were similarly well-handled. For commuters and frequent flyers, the Q45's low-frequency ANC is genuinely impressive and approaches the performance of headphones that cost twice as much.

Mid & High-Frequency Cancellation: The Q45 is less effective at blocking voices, keyboard clatter, and sudden sharp sounds. In a busy open office, we could still hear colleagues speaking at normal volume roughly 8–10 feet away, though their voices were significantly muted. The adaptive algorithm does not react instantaneously to irregular noise, and a thin band of higher-frequency masking hiss is audible when ANC is active at maximum. The hiss is not annoying when music is playing, but it is noticeable in silence. For comparison, the Sony WH-1000XM5 and Bose QC45 are more effective across all frequencies and do not introduce distracting hiss. However, they also cost $200–$300 more.

Transparency Mode: The Q45 offers a traditional transparency mode that pipes in environmental sound, plus a Talk Mode that enhances the frequency range of the human voice for brief conversations. Transparency is natural-sounding and useful for walking, cycling, and airport navigation. Talk Mode works well for ordering coffee or speaking to flight attendants without removing the headphones. Both modes are accessible via the NC button or the app. Wind noise reduction can be enabled in the app for outdoor use, though we found it only partially effective in strong breeze.

Wind Noise: Wind handling is a known weakness. In breezy conditions above approximately 15mph, the external microphones generate noticeable wind rumble in both ANC and Transparency modes. The wind noise reduction setting in the app mitigates the worst of it, but it does not eliminate the issue entirely. For outdoor runners and cyclists, we recommend disabling ANC entirely in strong wind. This is a common limitation of ANC headphones in this price class.

Microphone & Communications Test

The Soundcore Space Q45 features six microphones — four dedicated to ANC and two for call pickup — with AI-enhanced call technology and beamforming. We tested call quality in quiet rooms, noisy coffee shops, windy streets, and inside a moving car.

Quiet Environment: In ideal conditions, the microphones capture voice with good clarity and acceptable tone. Callers reported that we sounded clear and intelligible, with minimal background hiss. The beamforming focuses on your voice while rejecting some off-axis sound. Voice assistant recognition — Google Assistant, Siri, and Alexa — is reliable. The Q45's call performance in quiet environments is perfectly adequate for personal and professional calls.

Noisy Environment: In a busy coffee shop with espresso machines, music, and conversations, the AI noise reduction performed adequately but not exceptionally. Callers could hear us, but they noted some background noise bleed-through and a slightly processed quality to the voice. The microphones handle consistent background hum better than irregular sounds. For casual calls and video meetings, the Q45 is serviceable. For professional call center work or broadcasting, a dedicated headset with a boom microphone remains recommended.

Wind Conditions: Outdoor calls in moderate wind (5–10mph) were acceptable, with callers reporting occasional wind gusts but generally intelligible conversation. In stronger wind (15mph+), the microphones struggled significantly. The wind noise reduction setting in the app helps marginally, but we still had to shield the earcups or find shelter to maintain call quality. This is a common limitation of headphone microphones and not unique to the Q45.

Multipoint Call Handling: The multipoint connection handles incoming calls gracefully when not using LDAC. When a call comes in on your phone while you are listening to music from your laptop, the headphones automatically pause the laptop audio and switch to the phone call. After the call ends, music resumes. This switching takes approximately 1–2 seconds and works reliably. Remember: LDAC mode disables multipoint, so you must choose between hi-res audio and dual-device convenience.

Battery & Connectivity Test

We tested battery life under controlled conditions and real-world mixed use, measuring wireless stability, codec performance, and charging behavior.

Battery Life — Bluetooth, 60% Volume, ANC On: The Q45 delivered 49 hours and 30 minutes of continuous playback with ANC active — effectively matching Soundcore's 50-hour claim. With ANC off, we measured 64 hours and 45 minutes, very close to the 65-hour rating. With LDAC at 990kbps and ANC on, battery life dropped to approximately 37 hours — a significant but expected penalty for hi-res streaming. These numbers place the Q45 among the endurance leaders in any price category, surpassing the Sony WH-1000XM5 (30h), Bose QC Ultra (24h), and even the newer Soundcore Space One Pro (40h). For most users, the Q45 will last two full work weeks on a single charge.

Quick Charging: Soundcore's quick charge performance is excellent. A 5-minute charge from empty delivered 4 hours and 5 minutes of playback with ANC on — matching the advertised claim. A 15-minute charge delivered approximately 11 hours. A full charge from empty takes approximately 2 hours via USB-C. The Q45 cannot be used while charging, so you cannot run indefinitely on USB power. Given the exceptional battery life, however, this limitation rarely matters.

Wireless Range & Stability: Bluetooth 5.3 maintained a stable connection at 12 meters (40 feet) with clear line of sight. Through one interior wall, range dropped to approximately 8 meters. We experienced zero audio dropouts during 50+ hours of testing within the effective range. LDAC at 990kbps remained stable in indoor environments, though we noticed occasional brief stutters when walking through areas with heavy 2.4GHz congestion. Dropping to LDAC 660kbps eliminated these issues with minimal audible quality loss. AAC was flawless across all tested devices.

Multipoint Performance: Pairing two devices simultaneously worked flawlessly across iPhone 15 Pro, Samsung Galaxy S24, MacBook Pro M3, and Windows 11 laptop — but only when LDAC was disabled. The Q45 remembered previously paired devices and reconnected automatically. Switching between devices required pausing audio on the active device before the second device could take over. Call priority worked correctly. The LDAC-or-multipoint trade-off is the biggest connectivity limitation and one you should consider carefully if you use multiple devices daily.

Comparison with Competitors

The sub-$150 wireless ANC headphone market is crowded with compelling options. The Soundcore Space Q45 faces strong rivals from Soundcore's own lineup, JBL, and Sony. Here is how they stack up.

vs. Soundcore Space One Pro — $149.99: The Space One Pro wins on design refinement, ANC effectiveness (6-mic Adaptive 3.0 vs. 4-mic), folding compactness (FlexiCurve mechanism), and metal-reinforced build. However, the Q45 wins on battery life (50h vs. 40h with ANC), price (often on sale under $100), and included hard-shell case. The Q45 also has a more balanced default sound signature compared to the bass-heavy Space One Pro. For pure value hunters, the Q45 remains the smarter buy. For those who want the latest design and slightly better ANC, the One Pro is tempting.

vs. JBL Live 770NC — $149.99: The JBL wins on features like auto play/pause wear detection, JBL Spatial Sound, and Personi-Fi 2.0 hearing personalization. However, the Q45 wins on codec support (LDAC vs. no LDAC), battery life (50h vs. 50h with ANC, but 65h vs. 65h without), build quality (aluminum hinges vs. all plastic), and included hard-shell case. The Q45's default sound is more balanced, while the JBL is warmer and more bass-forward. These two are the closest competitors, and the choice comes down to whether you prioritize LDAC and build (Q45) or wear detection and spatial audio (Live 770NC).

vs. Sony WH-CH720N — $149.99: The Sony wins on weight (192g vs. 295g) and app ecosystem maturity, with slightly better midrange timbre. However, the Q45 wins on battery life (50h vs. 35h with ANC), ANC effectiveness, LDAC support, build quality, and included hard-shell case. The CH720N's non-collapsible design is also a significant travel disadvantage. For most buyers, the Q45 offers better value with more features and longer endurance.

vs. Soundcore Life Q30 — ~$59.99: The Q30 is the Q45's little sibling and an incredible value at under $60. It shares the same app, similar sound tuning, and decent ANC. However, the Q45 wins on ANC quality (adaptive hybrid vs. basic), battery life (50h vs. 40h with ANC), LDAC support, build quality (aluminum vs. all plastic), and included hard-shell case. The Q30 is the budget king, but the Q45 justifies its higher price with meaningful upgrades in noise canceling, codec support, and durability.

The Verdict: The Soundcore Space Q45 does not lead in any single category against all competitors — it is not the lightest, the newest, or the most feature-packed. But it leads where it matters most to budget buyers: in the combination of ANC quality, battery endurance, LDAC hi-res support, build durability, and overall value. No other headphone under $150 offers this complete a package, especially when found on sale below $100.

Pros & Cons

What We Loved:

The adaptive hybrid ANC is genuinely effective for the price, especially on airplanes and public transit, with both adaptive and manual modes available. Battery life of up to 65 hours is exceptional and eliminates charging anxiety entirely. LDAC hi-res codec support gives Android users wireless audio quality that competitors at this price cannot match. The aluminum alloy hinges and headband provide build quality rare in sub-$150 headphones. The included hard-shell travel case is a premium inclusion that competitors reserve for flagships. The 8-band custom EQ with 20+ presets unlocks genuine sound customization. The silk-and-ceramic drivers deliver energetic, engaging sound. Multipoint connection works reliably (when not using LDAC). Physical button controls are frustration-free. The 5-minute quick charge delivering 4 hours is a genuine lifesaver. And the overall package — ANC, sound, battery, build, and accessories — represents one of the strongest value propositions in wireless audio.

What Could Be Better:

The default treble is slightly bright and sharp, especially with ANC on, requiring EQ adjustment for long sessions. The midrange lacks the richness and forward presence of Sony and Sennheiser competitors. At 295g, it is heavier than ultralight alternatives like the Sony WH-CH720N. The headband cushion is thin and may cause crown pressure during marathon sessions. Wind noise handling is mediocre — outdoor ANC use in breezy conditions generates rumble. LDAC mode disables multipoint connection, forcing a choice between hi-res audio and dual-device convenience. The microphone is good but not great for professional calls. There is no virtual spatial audio for movies and gaming. And the ear cushions, while plush, can trap heat during summer use.

Final Verdict

After two months of daily use — flying across continents, grinding through open-office workweeks, commuting on subway trains, binge-watching Netflix, and listening to every genre from Beethoven to Bassnectar — the Soundcore Space Q45 has reaffirmed its position as the best budget ANC headphone under $150. Not because it is perfect. But because it understands exactly what budget buyers need and delivers it without apology.

The Q45 is not a headphone for audiophile purists seeking neutral reference sound — the Sennheiser HD 400S and Audio-Technica ATH-M50x offer flatter, more analytical signatures. It is not a headphone for bass fanatics who want physical rumble — the Sony ULT Wear and Skullcandy Crusher ANC 2 deliver more aggressive low-end. It is not a headphone for executives who need the absolute best noise canceling — the Sony WH-1000XM5 and Bose QuietComfort Ultra remain the business-class champions. It is not the newest option — the Space One Pro and JBL Live 770NC offer more modern feature sets.

It is a headphone for the smart buyer who wants maximum value. The commuter who needs ANC that actually works on a train. The student who cannot afford to charge every night. The traveler who wants a hard case and a foldable design. The Android user who wants LDAC hi-res without paying flagship prices. The listener who wants to tweak their sound without buying a $300 headphone. The person who has been burned by cheap plastic headphones that snap in six months and wants aluminum hinges that last.

At Devixo Store, we believe in making your choice effortless. We test every product thoroughly so you do not have to. The Soundcore Space Q45 has earned our highest recommendation for budget wireless ANC headphones in 2026. If you want adaptive hybrid ANC, 65-hour battery life, LDAC hi-res audio, aluminum build quality, and a hard-shell case in a sub-$150 package — buy it. Without hesitation.

Should you buy it? If you want the most complete ANC headphone under $150 — with noise canceling that works, battery that lasts weeks, hi-res wireless audio, and a build that survives daily abuse — yes. Without hesitation. The Soundcore Space Q45 is the budget ANC headphone that refuses to feel budget.
